Body roundness index (BRI) is a calculated geometric index used to quantify an aspect of a person's individual body shape. Based on the principle of body eccentricity , it provides a rapid visual and anthropometric tool for health evaluation.
The measurement is taken with the person standing upright, with arms hanging down loosely. The skin fold is pulled away from the muscle and measured with the calipers, taking a reading 4 seconds after the calipers have been released. [3] [4] The measuring point is halfway between the olecranon process of the ulna and the acromion process of the ...

The Corpulence Index (CI) (also Ponderal Index (PI) or Rohrer's Index) is a measure of corpulence, or of leanness in other variants, of a person [1] calculated as a relationship between mass and height. [2] It was first proposed in 1921 as the "Corpulence measure" by Swiss physician Fritz Rohrer [3] [4] and hence is also known as Rohrer's Index ...
If both are the same weight, the taller woman has a much lower body mass index; if they have the same BMI, the weight is distributed around a greater volume. A woman's bust measure is a combination of her rib cage and breast size. For convenience, a woman's bra measurements are often used as a proxy. Conventionally, measurement for the band of ...
A Body Shape Index (ABSI) [1] or simply body shape index (BSI) is a metric for assessing the health implications of a given human body height, mass and waist circumference (WC). The inclusion of WC is believed to make the BSI a better indicator of risk of mortality from excess weight than the standard body mass index .
Muscles with short fibers will have higher PCSA per unit muscle mass, thus greater force production, while muscle with long fibers will have lower PCSA per unit muscle mass, thus lower force production. However, muscles with longer fibers will shorten at greater absolute speeds than a similar muscle with shorter fibers. [2]
Poor posture can cause rounded shoulders because of the muscle imbalance [12] and uneven weight distribution in our upper body. [13] Long periods of time spent in positions that put undue strain on the shoulders and neck may wear out some of the muscles while weakening others.
